I have to do an extraneous equation with the problem I posted below. So far I did that but the teacher said I'm missing something. Can someone help me on what I'm missing to make it an extraneous solution

I think squaring a function may cause an extraneous solution. But you probably want to check with someone else about it.

OpenStudy (wintersuntime):

okay thanks

OpenStudy (usukidoll):

well you are right on the domain being restricted. because if our denominator is (x)(x+1) x can't be 0 and -1

OpenStudy (wintersuntime):

okay

OpenStudy (wintersuntime):

but I think to get the extraneous solution we have to do something to the numerator ?

OpenStudy (usukidoll):

An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. So it's like we need one x that's false for the equation .

OpenStudy (wintersuntime):

What do you mean by a root of a transformed equation?

OpenStudy (anonymous):

When you add, subtract, multiply, divide or square both sides of an equation you are transforming it into an equivalent equation.

OpenStudy (wintersuntime):

oh okay

OpenStudy (wintersuntime):

The teacher said I'm just missing something to make it an extraneous equation

OpenStudy (wintersuntime):

I feel like I have to square root something but Im not sure
